Automatic
random 3D bin picking

 

At each "picking" cycle, the stereoscopic (or triscopic) system sends to the robot the x,y,z position of the easiest part to pick up.

This "random 3D bin picking" operation is mandatory in a lot of production industries, to feed up conveyor belts, machines or robots with parts, in automated assembly lines.

Heavy, hot, fragile, complex shaped : All parts, randomly positioned, are quickly and precisely gripped out of the bin.

A specific optical system allows a reliable random 3D picking of various metallic & shiny bars.

Digitization &
3D reconstruction

 

The stereo system projects structured light onto the object and analyzes its reflections. This operation (very fast : 3/10^th s) is repeated as many times as necessary (depending on shape complexity), the object being rotated from a certain angle between each acquisition. Automatic fusion of all the acquired 3D point clouds creates a coherent set which finally gives, after being properly meshed , the very accurate 3D volume of the real object.

As an option, the grey or true colours can be applied to each 3D point, to render a "photo-realist" view of the 3D volume.

Dynamic monitoring of
3D displacements

 

The stereoscopic system localizes the whole set of targets in the viewed scene. It records in Real-Time (120 f/s) dynamic phenomenons and renders, after calculation, successive x,y,z positions of each target.

 

Alternate solution: A single camera records the whole sequence in 2D (Airborne systems). A prior stereoscopic analysis of the scene allows to render the whole 3D displacement data from the single 2D sequence.

 
Markets:

• Firms of Architects
  
• Civil engineering structures
  
• Tests laboratories
  
• Aeronautic studies

Field of view:As needed
Measurement pace: 120 frames/s
3D measurement precision: 1/10^th mm at 20m

Dynamic monitoring of
2D displacements

 

The stereoscopic system localizes the whole set of targets in the viewed scene. In Real-Time (90 f/s), it returns the very precise x,y coordinates of all target centers.

This "contactless" method replaces with high benefits the use of strain gauges, quite often difficult and time consuming to position, pricey in numbers, and/or non suitable for very small and fast 2D displacement studies.

 
Markets:

• Structural Health Monitoring
  
• Firms of Architects
  
• Civil engineering structures
  
• Tests laboratories
  
• Aeronautic studies

Field of view:As needed
Measurement pace: 250 frames/s or more (camera frame rate dependent)
3D measurement resolution: 2/100^thof a mm at 20m

Dynamic measurement
of 3D micro-distortions

 

The stereoscopic system records in real-time images of a surface, previously speckled by tiny paint spots. Afterwards, the image analysis and calculations of the image sequence returns the dynamic 3D cartography of the surface distortions.
